Language Support
CDex has support for several languages, the current distribution only packs a couple of language files to keep the file size of the distributable to an acceptable level, the language specific files(s) can be download here.
Select the language of your choice, put the downloaded language file into your CDex folder, and restart the application. From the Options->Language menu option the language of your choice should be selectable.

Miscellaneous downloads
Wmaudioredist.exe file: (if you want to use the WmAudio encoder of Microsoft, you might need this file as well):wmaudioredist.exe file

In some instances, you might need the MFC42.DLL and MSVCRT.DLL as well. I did not included it into the CDex zip file since most people already have this file on their systems. If you are missing this file, download the zip below, unzip it into the windows system directory.MFC42.DLL zip filemsvcrt.dll zip fileoleaut.dll filews2_32.dll file

Unzipping
If you need a program to unzip these files, try 7-Zip.
7-Zip is a file archiver with a high compression ratio.http://www.7-zip.org/
